Cool!  Have you announced this effort on the freegis list?  I think it would
be a good idea.

Of course you are welcome to use shapelib and PROJ.

I would like to encourage you to build on GDAL and OGR for raster and
vector format access.  Of course use of GDAL and OGR might be against your
lean and mean motto, but it would give you a bunch of capabilities in short
order rather than tying to a bunch of ideosyncratic C libraries for different

OGR also contains a higher level coordinate system abstraction built on PROJ.4.
